A Northern Territory aviation company owned by the prominent Paspaley pearling family is downsizing and shedding staff in the face of a mining industry downturn.

Pearl Aviation – which, on its website says it employs more than 200 staff – has confirmed in a statement to the ABC that it is restructuring its Darwin operations.

"Pearl Aviation's Darwin-based charter operations will be downsized in response to the reduced demand for small aircraft, which has come about with the decline in the resources sector," the statement said.

"Pear Aviation is working to minimise the impact on jobs and to support affected individuals and families."

Nearly two years ago, Darwin airline Vincent Aviation collapsed and about 100 staff lost their jobs.

Pearl Aviation has not yet responded to questions as to how many redundancies there will be, when they will be rolled out, and whether they will be voluntary or target specific positions.

You have no doubt been hearing a lot about the Paris Agreement and know that it pertains to climate change, but are too embarrassed at this stage to ask for an overall explanation of what it's all about.
